Definitions

  • the invention relates to a device for treating filament yarn by means of a nozzle having a yarn channel, which is formed as an open and divided nozzle with threading and Mediumzuschreibkanal in the yarn channel and a method for treating filament yarn by means of a yarn channel having a nozzle, which divided open nozzle with free threading slot and medium feed channel is formed in the yarn channel.
  • the invention further relates to a knotted yarn, a migrated yarn and a false twisted yarn.
  • the swirling purpose is primarily to improve the cohesion and also to increase the reliability, eg when winding and unwinding the filament yarn.
  • the aim of the migration is to give the thread a sufficiently good cohesion in the immediately following processing of the yarn, so that the subsequent direct interventions can be carried out without disruption.
  • the filaments in the thread composite are only slightly crossed, so that no individual filaments protrude from the thread.
  • migration was carried out using normal vortex nozzles. It was worked for a swirl with the worst possible operating conditions, so that almost no knots emerged.
  • Migration and swirling have the sole purpose of improving the cohesion of the single filaments of the thread for yarn processing, as well as the winding and unwinding with the many deflections.
  • the goal is to prevent malfunctions and yarn breakage without creating a disturbing effect on the finished fabric through the knots.
  • the aforementioned treatments with single or multiple nozzles are used.
  • the nozzles are used as double nozzles.
  • the number of nozzles corresponds to the number of yarn runs. These can be 6 to 12, 16, 20 and recently even 24. The next goal is a doubling to, for example, 50 yarn runs.
  • a nozzle body is in the U.S. Patent 5,157,819 shown.
  • the nozzle body consists of a larger number of flat plates, which can be clamped together via a screw connection.
  • the yarn channel is formed by means of through holes perpendicular through each plate. The through holes are precisely matched in each plate, so that in the assembled state through all plates through a cylindrical, closed yarn channel is formed.
  • plates with and without air supply channels can be formed and clamped together as a package with two end plates. It is a closed nozzle without threading slot.
  • Aim of the solution according to U.S. Patent 5,157,819 was the largest possible number of air supply ducts, whereby it was intended to produce knot yarn as well as false twisted yarn with the same nozzle concept.
  • the state of the art shows an open, split air nozzle for the production of knotted yarn.

  • the nozzle body has an air supply channel and a transverse bore for blowing the treatment medium into the yarn channel.
  • yarn channel profiles are mounted both in the nozzle coiler and in the cover plate. Only in fauxgabaut state is formed between the nozzle body and the cover plate of the yarn channel. Between the two bodies, a gap is provided, which forms the Einfädelschlitz on the side facing away from the air supply element.
  • the nozzle is a typical swirl nozzle with approximately central and vertical arrangement of the air supply in the yarn channel.
  • both nozzle body and cover plate should be used two or more times, which is a disadvantage in terms of a narrow pitch for the yarn runs.
  • a special case for the application of turbulence are water treatment plants. 500 to 2000 parallel yarn runs are treated simultaneously in very close pitch.
  • the EP 0 216 951 shows such a special device for swirling multifilament threads.
  • the turbulence takes place on two levels, an upper level and a lower level.
  • the Verwirbelungskanäle are arranged for the corresponding number of yarn runs in a very small space, so that the crowd of warp threads can be fed with a very close distance.
  • the swirling device has a number of parallel juxtaposed slots. These are formed between disks and spacers of a nozzle rod.
  • the individual disks have an annular shape, wherein compressed air is supplied to each disk above the central region and supplied via respective transverse bores to the individual swirling zones formed as slots.
  • the threads are transported at a distance from the slot bottom, in the area of influence of the blown air, through the device.
  • the discs have both inlet side and outlet side yarn guide. With the assembly of a plurality of discs with intermediate elements, end to end, so-called nozzle rods are formed.
  • the solution is extremely space-saving. The result is a pitch for the yarn runs in the order of 4 mm. So that the warp threads can not jump out of the treatment slits, a wire is pulled through in the outer area of the slits.
  • the discs are made of ceramic, especially oxide ceramics. This results in a long service life, wherein the ceramic discs are produced by the molding process and then fired.
  • the swirl force of the blown air is used to over an immediately upstream thermal treatment by heating and cooling of the yarn to change the molecular structure of the individual filaments permanently, so that the yarn is a considerable bulk.
  • the false twist is on the EP-PS 0 532 458 With reference to false twisting, the filament yarn and the finished fabric should be given a bulky, textile character.
  • the inventors have now taken on the task to seek solutions to develop low-cost nozzles for the yarn treatment in the context of open nozzles, even for divisions between two or more parallel yarn runs in the field of a few millimeters, the concept should be used in particular for single or poppeldüsen.
  • the device according to the invention is characterized in that the nozzle is formed by nozzle / cover plates which each have a nozzle and cover plate side can be assembled on a medium supply element and form a yarn channel between two adjacent nozzle / cover plates.
  • the inventive method is characterized in that the yarn for the treatment between two same, together forming a yarn channel plates is guided, wherein the plates are sealed to each other and with respect to the medium supply side.
  • a knot or migrated yarn in particular as a microfilament yarn, is characterized in that , for the treatment , it is guided between two identical plates which together form a yarn channel and a knotted yarn or migrated yarn is produced.
  • a false-twisted yarn is characterized in that it has been guided and false-twisted for the treatment between two equal plates forming a yarn channel.
  • the nozzle / cover plates of a nozzle are the same.
  • Each of the nozzles / cover plates has the two functions nozzle plate and cover or baffle plate in it. Separate cover plates, omitted.
  • the plates can be made with very small external dimensions of eg 1 cm by 2 cm and a thickness of 4 mm or less.
  • the simple plate shape results in their production, especially in ceramics, enormous relief, since this now with the can be made much cheaper injection molding. At least the blanks for the plates can be produced in larger quantities and thus cheaper.
  • the plates of a nozzle can be made identical, they can be installed rotated in the case of a single nozzle of 180 °, so that with the still unused Garnkanalprofiten with respect to the wear in their life a doubling can be achieved.
  • the new solution allows, as will be explained, the production of the plates by injection molding, which is much cheaper than the pressing method, as in accordance with EP 0 216 951 .
  • the second enormous advantage lies in the fact that the yarn channel, which at the EP 0 216 951 is designed as a mere slit, according to the new invention, the specific treatment can be adjusted.
  • the slices of the EP 0 216 951 have the enormous advantage that two threads form between two discs.
  • the disadvantage of the solution according to EP 0 216 951 is, however, that with the simultaneous integration of the yarn guide and the air supply in the plate concept almost palm-sized slices arise, which can be produced only by pressing.
  • the new plate concept can be used in various treatment processes such as swirling, migrating, false twisting and other textures on filament yarns. It can also be used in reed plants as a multiple nozzle and in texturing plants as a single or double nozzle, but also in stretching plants and false twist texturing plants.

  • each of the at least two plates has a medium supply channel, which can be activated individually via corresponding connection openings of the medium supply element, so that the free outflow of the unused air supply opening is avoided.
  • Each of the at least two plates of a nozzle is identically formed at least with respect to the yarn channel profiles and each has a nozzle plate side and cover plate side yarn channel profile, which forms a yarn channel only in the assembled state. Because only two plates together form a yarn channel, there are two unused outer sides for each pairing of two or more plates. In the case of a simple nozzle, this has the great advantage that, after greater wear on the active yarn channel profiles, both plates can be installed turned by 180 °, so that the service life of a nozzle can be doubled.
